Implantable Medical Device Developer and Manufacturer
On December 16, 2024, CIRCULINE®, a dialysis artificial blood vessel product independently developed by Shanghai Changdy Medical Co., Ltd., a wholly-owned subsidiary of JIANGSU BIODA LIFE SCIENCE Co., LTD. ("BIODALS"), an outstanding company invested in by Daoyuan Capital, successfully obtained the Innovative Medical Device Registration Certificate (Registration No. 20243132518) issued by the National Medical Products Administration, marking the official entry of this innovative product into the market.
Since its establishment, BIODALS has been focusing on the research, development, and production of high-end implantable and interventional medical devices. It has successively established wholly-owned subsidiaries, Shanghai Changdy Medical Co., Ltd. and Behelia. Its product portfolio includes the VASOLINE® artificial blood vessel, VASOPATH® disposable strip retractor, MONOKNIT™ hernia repair mesh, and VASO™ non-absorbable surgical suture. The recently approved dialysis artificial blood vessel product marks another significant breakthrough for the company following the first Chinese registration certificate for a large arterial artificial blood vessel.

CIRCULINE® (China Medical Device Registration No. 20243132518)It is a textile-type artificial blood vessel made by the organic combination of medical-grade high-elastic silicone and expanded polytetrafluoroethylene (ePTFE), featuring an innovative three-layer structure for dialysis. The inner layer is an ultra-thin ePTFE artificial blood vessel with molecular support rings, offering excellent biocompatibility and providing an effective anti-thrombosis channel for blood flow. The middle layer consists of medical-grade high-elastic silicone, which quickly regains its original shape after deformation, ensuring optimal needle-hole closure after dialysis puncture. The outer layer is a braided polyester artificial blood vessel, characterized by excellent suture ability, providing speed and necessary strength for suturing during surgery.

Dialysis Grafts Suitable for Arteriovenous Fistula Creation. As China's population aging process accelerates, the number of related patients continues to increase, and the market demand for dialysis grafts is also growing. For a long time, China's dialysis grafts market has mainly relied on imports. The approval of the CIRCULINE® graft product this time not only enriches the company's product line but also marks an important milestone for BIODALS in the medical device field. More importantly, it will effectively break the Western technology monopoly and alleviate the issue of heavy reliance on imported products in the Chinese market.
